This 2026 guide groups tools by their role in a stream. StreamCat is a third-party Windows livestream assistant for Douyin and Bilibili. It supports simultaneous connections to those platforms and can work alongside your broadcast setup. Douyin support here refers to Douyin in mainland China.
Set up broadcast video and audio first
Check your platform's broadcasting requirements, then choose how to organize video and audio. OBS Studio supports recording and live streaming with sources such as cameras, windows and images. Its official website provides current features and system requirements: https://obsproject.com/ .
Once the broadcast is working, add chat display, spoken messages and activities. Keep track of which application handles each part so that audio and overlays are easy to configure.
Check live chat from both sides of the stream
StreamCat, also known by its project name StreamCatDual, is a WPF-based Windows desktop livestream assistant. It is installed and runs locally on the streamer's computer, with chat and audience interaction support for Douyin and Bilibili. Platform connections and features that use online services still require internet access.
The host and the audience need different views. The host needs readable messages in a convenient place. The audience needs a chat overlay that leaves the main content visible. If you use speech playback, check its rules, voice and output device separately.
StreamCat provides floating chat, speech playback and stream layout settings. Start by connecting a room and checking a message, then use the OBS browser-source guide to set up the audience view.
Choose chat interaction software around an activity
Use a concrete idea when evaluating an interaction tool: play a prepared sequence after a gift, show a viewer companion during conversation, or award a decoration for a themed event.
StreamCat's gift-triggered action chains arrange actions with configured order and timing, using audio, media and scene actions. Viewer companions add another element to the conversation. Monthly and event collections let viewers display earned decorations. Start with one or two features and explain how viewers participate.
Test participation before choosing a chat game tool
Check how viewers join, how messages are recognized and where results appear. Platform events, the installed version and configuration all affect an activity.
Before a broadcast, test a complete round using an activity supported by your version. Read StreamCat's game information, then follow the getting-started guide for the initial connection.
Match the tools to your stream
- Gameplay: prioritize video, audio, readable chat and alerts that leave room for the game.
- Conversation: try chat display, speech playback and viewer companions at a pace that suits the host.
- Themed events: prepare rules, gift-triggered sequences, collectible decorations or supported games, then test the beginning and end of each activity.
- Simultaneous Douyin and Bilibili streams: check each connection and its events before configuring display and interaction rules.
Compare livestream assistants by testing the same task in each one. Confirm platform support, message display and the activity you plan to run, then decide which tools belong in your setup.
